Verbena plant named ‘Rap Horose’

ABSTRACT

A  verbena  cultivar particularly distinguished by its rose-colored flowers, upright habit and mildew tolerance is disclosed.

Genus and species: Verbena hybrida×Verbena tenuisecta.

Variety denomination: ‘Rap Horose’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of verbena, botanically known as Verbena hybrida×Verbena tenuisecta, and hereinafter referred to by the cultivar name ‘Rap Horose’. The new cultivar originated from a hybridzation made in the year 2002 in Gilroy, Calif. The female parent was ‘Oxena’ (also known as ‘Babylon Red’) (U.S. Plant Pat. No. 13,126) while the male parent was ‘1352-1’, a purple proprietary verbena line (unpatented).

The new cultivar was created in 2002 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a two-year period. The plant has also been trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

DESCRIPTION OF PHOTOGRAPH

This new verbena plant is illustrated by the accompanying photograph which shows overall plant habit, flowers, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Rap Horose’. The data which define these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 5-month-old plants grown in one-gallon pots in a poly-covered greenhouse in the fall/winter season. Color readings were taken in the greenhouse in the late winter season under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition). Texture description details were observed with a dissecting microscope.

COMPARISON WITH KNOWN CULTIVARS

‘Rap Horose’ differs from the female parent ‘Babylon Red’ (U.S. Plant Pat. No. 13,126) by having smaller flowers and a more upright, less spreading habit than ‘Babylon Red’. ‘Rap Horose’ differs from the male parent ‘1352-1’ (unpatented) by having a rose-colored flower rather than a purple-colored flower. In addition, ‘Rap Horose’ has a more upright, vigorous habit than ‘1352-1’.

‘Rap Horose’ differs from the commercial variety ‘Bodcompin’ (U.S. Plant Pat. No. 15,242) by having a rose-colored flower rather than a pink-colored flower. In addition ‘Rap Horose’ has a flatter, fuller habit, shorter internodes and a less incised leaf than ‘Bodcompin’.
